Without repeating whats on the video just let me simply say if youre wanting active noise cancelling headphones, "THESE ARE THE ONES"! Aha! I bought a pack of these slippers to use for guests at my new apartment. I can wear a 7. I love how cute this is. But, the action is solid. Best of all, these shoes are true slip-ons. I figured I couldnt possibly be the only person to think that these shoes were unfathomably uncomfortable. Shoes:These shoes are a true matte black. But they did hold the bikes with no issues.
